Summary:An inkjet printer and method therefore including a detector to monitor a quantity of release agent applied to a spreader drum. The inkjet printer includes a drum maintenance unit which applies the release agent to the spreader drum with a metering device, such as a metering blade, and determines a flow rate of unused release agent returned to a release agent sump. The determined flow rate of release agent provides a determination of the quantity of release agent applied to the spreader drum. Upon the determination that too much release agent has been applied based on the flow rate, an alert signal is generated indicating that the metering blade should be inspected and replaced if necessary. Monitoring the amount of release agent applied to the spreader drum in this way enables a more robust printing and in-line coating system.
